Rhodeus Sericeus Amarus Bloch, 1782; Monitoring Elements in the New Natura 2000 Context in Croatia

Abstract

The action framework at the European Union level for the conservation of biodiversity was set up based on the Birds Directive (79/409/EEC) and Habitats Directive (92/43/EEC). One principal element of the implementation of these two significant Directives in Croatia is the set up of a Natura 2000 network of protected areas, a network which should be based on a specific monitoring plan at Croatian national level for each species which is considered of community interest. In this general context, this study suggests a set of monitoring elements for Rhodeus sericeus amarus for the Croatian Continental Biogeographical Region. The suggestions are based on eight selected criteria: Croatian national borders proximity sectors overlay; very good quality populations of Rhodeus sericeus amarus in terms of population density and structure (e.g. protected areas) in characteristic good habitats; habitats which need ecological reconstruction to allow this fish species populations structure ameliorate or natural repopulation; key sectors with importance for connectivity (e.g. lotic sectors between different important sectors, rivers confluence areas, etc.); sectors influenced by human impact like: industrial pollution point sources, sectors influenced by agricultural diffuse sources of pollution, sectors influenced by habitats modifications (watercourses remodeling, watercourses regulation, etc.), geographically extreme monitoring sections in the most-upstream and mostdownstream sections of the rivers, in this species range and in the near outer proximities of these extremes
